A chemical reaction typically involves the breaking and forming of chemical bonds between atoms. It starts with reactant molecules colliding and forming temporary bonds, leading to the breaking of existing bonds and rearrangement of atoms to form new products. This process can involve multiple intermediate steps and may release or absorb energy in the form of heat or light. The reaction continues until a state of equilibrium is reached, where the concentrations of reactants and products remain constant over time. **

The Tollens test is a chemical test used to detect the presence of aldehydes in a given compound. It involves the reaction between an aldehyde and Tollens' reagent, which is a solution of silver nitrate in ammonia. If an aldehyde is present, it will reduce the silver ions in the Tollens' reagent to form a silver mirror on the inner surface of the test tube. This test is commonly used in organic chemistry to distinguish between aldehydes and ketones based on their reactivity with Tollens' reagent. **
